I saw this problem on my debian/testing system. I fixed my system yesterday based on Steve Langasek's comment to this bug report.
Steve's analysis appears accurate for my account. I found the WebWizard references in the old (very old) ~/.openoffice/1.0.1/ directory. The same reference appears in ~/.openoffice.org2/user/basic/{dialog,script}.xlc.
Instead of removing all of my OOo configuration, I simply commented out the offending <library:library> tag in the two xlc files. Now I don't see the error.
